Design outcomes

Primary

MeasureTime frame
Autonomic functions (i) Heart rate variability (ii) Respiration rate (iii) Attention and Memory (iv) Psychological (v) Visual Analoge scaleTimepoint: Total duration of experiment: approximately 30-35 minutes Primary outcome variables i.e., Heart rate variability and Respiration rate will be assessed at different time points i.e. Pre approximately 5-6 minutes, During approximately 11 minutes [2 epochs of 5 minutes each with 1 minute rest] and post approximately 5-6 minutes in experimental and control sessions respectively.

Secondary

MeasureTime frame
Cognitive outcomes (i)Measure of attention using Six Letter Cancelation Test (SLCT) (ii) Measure of Memory using Rey Auditory Verbal Learning (RAVLT) Timepoint: Total duration of experiment: approximately 30-35 minutes secondary outcome variables i.e., cognitive will be assessed at different time points i.e. Pre approximately 5-6 minutes and post approximately 5-6 minutes in experimental and control sessions respectively.;Psychological outcomes (i) Quality of practice of the intervention session (ii) Feelings of anxiety, calmness, discomfort and relaxation through visual analog scale (VAS)Timepoint: Total duration of experiment: approximately 30-35 minutes secondary outcome variables i.e., psychological variables will be assessed after post session approximately 5-6 minutes in experimental and control sessions respectively.;Psychological outcomes State anxiety using Spielbergers State and Trait Anxiety Inventory sub-scale State [STAI-S]Timepoint: Total duration of experiment: approximately 30-35 minutes secondary outcome variables i.e., psychological variables will be assessed at different time points i.e. Pre approximately 5-6 minutes and post approximately 5-6 minutes in experimental and control sessions respectively.
